In-Car Mounting Notebook PC for Oziexplorer

I have an NP Pajero (current model) and would dearly like to have my notebook PC mounted so that either or the driver/front seat passenger can use it for navigation while on the run. ie moving map feature of Oziexplorer and additional features of Travel Mate.
I designed and built a prototype "desk" that can be quickly clipped in and out of the upper glove box. It work very well but I've abandoned this idea because of safety issues for the front seat passenger. The desk itself is a hazard and the screen would be directly in front of the passengers side air bag.
I am looking at three solutions but would like to hear from others who have had to solve this problem.
a) "Mobile Desk" make a stand for notebook PCs but the response about suitability for the Paj was not good.
b) I can buy a PDA (say Ipaq) and run Oziexploer CE but Travel Mate doesn't run in CE.
c) I can go to Liliput screen and find a way of mounting it. Perhaps using the "Clic-on" product by Neovox

There's not a lot of cost difference in these three ideas and each has it positives and negatives.
The notebook, itself, is relatively large and can get in the way of comfortable and safe operation of the vehicle if mounted so that the screen can be seen, but the screen is large and I can have all my maps on the hard drive.
The PDA screen is small and I find it difficult to get the overview that I would like. It's also limited in memory but it is portable and can be used for other functions such as its name implies.
The Lilliput screen needs a mouse because the touch screen, especially in a moving vehicle, is hard to operate. The screen is still a little small although better than the PDA and I don't have the problems with memory.
Any and all comments/suggestions welcome.
